UNITED STATES FRED M. MOHENRY AND THOMAS S. WILKES, OF CORVALLIS,OREGON; SAID ASSIGNOR. TO SAID MCHENRY PATENT oFFicE l d WILKEs SANITARYTOILET Application filedA May 2,

The invention relates to improvements in toilets of the general type inwhich a charge of ,chemicals is supplied to a point below the seat eachtime the toilet is used.

One object of the invention is to provide a new and improved means fordischarging the requisite amount of chemical each time the seat cover israised.

Another aim is to provide a receiving pan for the eXcrement andthechemical, said pan normally hanging yin a discharge position within areceptacle under the seat but being antomatically movable to an elevatedreceiving position each timefthe seat cover is raised. The constructionherein disclosedis-for the purpose of handling a liquid chemicalcontained normally in a tank, and still further aims are to providevvunique' means yfor discharging the liquid in measured charges fromsaid tank, to prevent further discharge of liquid from the tank whensaidv liquid has reached a predetermined low level, and to operate theliquid-discharging means from'the seat cover in such a way that openingof the ylatter isretarded when the liquid discharge means is heldagainst functioning, thereby signifying that it is time to recharge thetank.

With the foregoing and minor objects 1n view, the invention resides inthe novel subject matter hereinafter described and claimed, descriptionbeing accomplished by reference to the accompanying drawing.

Fig. 2 is a front elevation.

Fig. 3 is a vertical sectional viewon line '3 3 of Fig. 2.

The drawings above briefly described illustrate the preferred form ofconstruction and while such construction will be herein specificallyexplained, it is to be understood that 1929. Serial No. 359,960.y

within the'scope of the invention as claimed, variations may be made. v

In the drawings, a continuous wall 10 is shown supporting a seat 11andprojecting a suitable distance above a ioor 12, and below this oor isa receptacle 18 for liquefied excrement and the liquefying andgerm-killing chemical, said receptacle being provided with a dischargepipe 14 to a drainage -bed or any other desired point of discharge.Immediately under the seat 11 is an lappropriate lhopper wall 15, andsomewhat behind this wall 15, is a rock shaft 16, at least one end ofwhich projects to theexterior of the wall'lO. Secured to'this shaft isashallow imperferatechemical and excrement receiving pan 17 which isnormally lowered to the discharge position seen i-n full lines in Fig.3. "Provision is made however for automatically raising said pan 17 to'the dotted line position of Fig. 3 when the seatv cover'18 is raised.In the present showing, a wheel 19 is secured on one end of the shaft16, and a link 2O connects said wheel with the cover 18 to effect upwardswinging of the pan 17 when said cover is raised and downward swingingof'said pan when the, cover 1s again lowered.

A tank 21 for liquid vchemical is mounted behind the parts abovedescribed, said tank being provided with a chemical-conducting pipe 22leading to a point at which it maydis- .charge into the pan 17 when theklatter is predetermined quantity of the liquid chemical and kdumping itinto the funnelk23 each time the pan 17 is in position to receive suchchemical. At opposite sides of `the 'bucket 24 we provide the latterwith a lowerl slide 25 and with an upper slide 26', a pivotal connectionbeing provided between the two lower slides and the bucket. Preferably,the

lower slides 25 are in the form of eyes secured to thevends of a rod 27which pivotally supports the bucket 24, and Vby preference theV upperslides 26 are in the form kof eyes secured to-said bucket. Verticalguide rods 28 provide a track for the bucket, said guide rods l.beingsecuiedin the tank 21 and having their upper ends 29 curved laterally topoints near thej upper end of the funnel'23. The slides 25-26 areyengaged withV the rods 28 and when the bucket 24 is elevated as seen inFig. 6, the slides 26 travel'onto the rodends29, thereby tilting saidbuckettoa discharging Y position, infwhichit dumps into the funn nel 23.
